Supported foam-silver catalysts for alcohol partial oxidation

Structural, mechanical, gas-dynamic and catalytic properties of silver catalysts supported on foam ceramics have been studied. The foam catalysts have high gas permeability, mechanical strength, and low density. Catalytic activity and selectivity of the foam catalysts in the process of oxidation of...

More Information
Summary:Structural, mechanical, gas-dynamic and catalytic properties of silver catalysts supported on foam ceramics have been studied. The foam catalysts have high gas permeability, mechanical strength, and low density. Catalytic activity and selectivity of the foam catalysts in the process of oxidation of methanol to formaldehyde exceed the characteristics of the commercial crystalline and granulated catalysts. Different electronic states (ions, charged cluster, crystals) of silver on the catalyst surface have been studied by the method of UV–visible spectroscopy.
